Benefits of technology

It describes an improvement over current methods used by networks when trying to balance their workload with other servers or devices connected through different communication paths. By analyzing all possible combinations between these connections, we aimed at finding ways to allocate more hardware without interrupting any services being served from them.

Problems solved by technology

The technical problem addressed in this patented paper relates to optimally assigning hardware resources among VMs while avoiding overloading any one's physical assets due to excess demand. Existing methods have limitations including fixed assignment scheduling algorithms, limited loading capacity, and inflexibility issues related to virtual machine migration.

Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] When multiple virtual networks share the physical network, after the physical network has been running for a period of time, multiple virtual networks run on the physical network at the same time, sharing physical resources. The virtual networks are isolated and occupy the allocated node and link resources independently during operation without interfering with each other. Due to the continuous arrival or departure of virtual network requests, the resource loads of physical nodes and links are also constantly changing, which may eventually lead to unbalanced physical resource loads within a certain period of time. This embodiment adopts a virtual resource remapping...

Abstract

The invention discloses a method for remapping virtual network resources, and relates to the technical field of virtual networks. The method comprises the following steps of: acquiring a key virtual node periodically, wherein the key virtual node is a virtual node in a virtual node set which is born by a physical node having a resource utilization rate greater than a threshold value; mapping resources of the key virtual node to a physical node having the resource utilization rate smaller than the threshold value, so that a resource load of a physical network is balanced; and remapping resources of a virtual link which is connected with the key virtual node. According to the method, a whole physical resource load is analyzed periodically, whether virtual resource is required to be remapped is judged, and part of key virtual nodes which cause unbalance of the physical resource load are selected to be remapped during remapping, so that the conventional physical resources can be integrated, the physical resource load can be balanced, the receiving rate of virtual network requests is improved, time consumption and computation cost can be saved, and the influence caused by the interruption of virtual network normal service can be maximally reduced.
